The paper analyzes some generic features of industrial dynamics whereby innovative change is carried, stochastically, by new entrants. Relying on the formal representation suggested in Winter, S.G., Kaniovski, Y.M., Dosi, G., 1997. A Baseline Model of Industry Evolution. [Interim Report IR-97-013/March, International Institute for Applied Systems Analysis, Laxenburg, Austria], it studies both the asymptotic properties of such processes and their appropriability to account for a few empirical stylized facts, including persistent entry and exit, skewed size distributions and turbulence in market shares.
